ABSTRACT:
A thermal printing head of the planar type which comprises a silicon substrate, a plurality of heat-generating elements provided in the silicon substrate and a heat-insulation layer of silicon dioxide which is provided around each heat-generating element. The heat-insulation layer of silicon dioxide has an excellent heat-insulation characteristic, so that heat which is generated from the heat-generating elements is prevented from flowing to neighboring heat-generating elements whereby distinct patterns can be printed on a thermosensitive paper.
